Safe Listening
Use of these earphones at full volume on portable music players
is within OSHA Permissible Exposure Limits (PEL) for 10 ½ hours
per day (52 ½ hours per week). Because of the noise-isolating
properties of the eartips (NRR=22 dB for 3-ange eartips and
NRR=27 dB for foam eartips) ambient (industrial) noise
(up to 102 dB for 3-ange eartips or up to 108 dB for foam eartips)
has a negligible eect on overall noise dose.
The HD5 Safe Listening Earphones have been tested in accordance
with the EN50332-2:2013 sound system equipment: Headphones
and earphones associated with personal music players —
Maximum sound pressure level measurement methodology.
The acoustic output of the HD5 is more than 20 dB below the
maximum limit in EN 60950-1/A 12:2011 Information technology
equipment - Safety -- Part 1: General requirements. Because of the
noise-isolating properties of the eartips (SNR 27 to 28), ambient
environmental noise up to 108 dB has a negligible eect on overall
noise dose.

Warnings
Failure to follow these recommendations may severely reduce
the amount of hearing protection provided.
• Earphones should not be used where there is a risk that the
cables can be caught up during use.
• Secure connecting cables away from entanglement hazards.
• Eartips t ear canal diameters of 6-14 mm. See “Selecting
an Eartip” section for details.
• Eartips must be tted, adjusted and maintained to the
manufacturer’s instructions to achieve the expected attenuation
and hearing protection.
• Use hearing protection at all times in noisy surroundings.
• Make certain that hearing protection provides adequate
protection for the noisy environment.
• Eartips are reusable. Regularly inspect the eartips to assure
their continued serviceability.
• This product may be adversely aected by certain chemical
substances. Further information should be sought from the
manufacturer.

Warnings (continued)
Human ear canals are about an inch long and Etymotic eartips
are designed to seal deeply in the ear canal. This may feel slightly
uncomfortable at rst, but should become comfortable with
repeated use. Discontinue use if any discomfort persists.
In rare instances an eartip may come o in the ear canal when
removing the earphone. If this should occur and the eartip cannot
be easily removed, it is recommended that you promptly contact
an audiologist or other medical professional. A professional can
use blunt tweezers to remove the eartip.
Consult an audiologist or physician if you have excessive ear wax,
diculty inserting the eartips, or discomfort after prolonged use.
Be aware of the environment you are working in and know the
hazards of over protection as well as under protection.

The eartip that is most comfortable is the likely choice, but it must
seal well for maximum protection. Important: Sound quality, full
bass response and noise isolation all depend on a good eartip seal
in the ear canal.
All Etymotic eartips are designed to be safely inserted into normal,
healthy ear canals. Do not insert anything into your ear canal if you
have discomfort or foreign material in your ears.
When changing

Insertion
Make sure the eartip is clean.
• When using foam eartips:
Roll down or compress foam
before inserting (Fig. 1).
• Pull the ear up and out while
inserting (Fig. 2).
• Twist and push gently until the
eartip seals in the ear canal.
• Hold the eartip in place for about
5 seconds while foam expands to
create a tight seal in the ear canal.
• When using 3-ange eartips:
Moistening may ease insertion.

Maintenance
Visually inspect your eartips before each use for signs of
discoloration (soiling) and note any changes in exibility.
Eartips that display any of these signs or other signicant wear
should be replaced. 3-ange eartips should be replaced every
3 to 6 months with average use. For heavy use (8-16 hours/daily)
they may need replacement in 3-6 weeks.
Foam eartips typically need to be changed more frequently than
3-ange eartips. Individual experience will vary, depending on
total use time and environmental conditions.
• Examine eartips after each use.
• Do not immerse earphones in water.
• Do not clean with harsh chemicals. Alcohol is not recommended.
• 3-ange eartips can be removed and cleaned in mild detergent
before reattaching. Dry eartips thoroughly before reattaching.
• Do not expose to extreme heat or moisture.
• Avoid dropping or hitting on a hard surface.
• Use only accessories from Etymotic Research, Inc. to ensure
continued performance to specication.
